| dc.description.abstract | This study investigated the levels of pendimethalin and cypermetrin residues in tomato sold in Malete market, Moro Local Government Area of Kwara State. Tomatoes were randomly collected from five different vendors in Malete market and analysis was performed using the QuEChERS (Quick, Easy Cheap, Effective, Rugged and Safe) method followed by chromatographic analysis using high performance liquid chromatography (HPLC) coupled to ultra-violet (UV) detector. Method validation of the study showed a linearity of the analytes which ranges from 5 – 500 μg/kg, with correlation coefficients greater than 0.999. The average recovery ranges from 75.6 to 111 % with relative standard deviation (RSD) from 2.74 to 9.03 %. The results indicated the presence of cypermethrin in analyzed samples at concentrations lower than the permissible maximum residue levels. | |
